VIBRATING APPARATUS FOR lNKlNG-ROLLERS.

SPECIFICATION forming part of Letters Patent No. 411,859, dated October 1, 1889.

Application filed March 18, 1889- Serial No 303,752. (No model.)

To aZZ whom it 12mg; concern:

- Be it known that I, SAMUEL G. Goss, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have inventeda new and useful Improvement in Vibrating Apparatus for Inking-Rollers, of which the following is a specification, reference being had to the accompanying drawings, in whichto Figure 1 is a side elevation of the inking portion of a printing-press. Fig. 2 is a rear view at the end of the inkin g-roller to which the operating devices are applied. Fig. 3 is a plan View of a similar portion of the press. Figs. 4: to 14., inclusive, are details which will be hereinafter explained.

- The object of this invention is to improve the construction and operation of the vibrating ink-rollers of the inking apparatus of a printingpress, so as to insure a more even and perfect distribution of the ink upon the inking-cylinder, and to improve the devices for operating the vibrating rollers, which I accomplish by means of the apparatus here- 2 5 inafter described, and the nature of which will be pointed out in the claims.

' In the drawings, A. indicates the framing of the press, which is made in any suitable manner, and of which a portion only is shown.

13 indicates the ink-distributing cylinder.

C is the form or plate cylinder, and G the type-inking rollers, which, with the rollers E F F, are made in the usual manner and of the usual material.

D indicates the ink-fountain, which is provided with the usual take-up roller K and intermediate roller K. This fountain and the feedrollers are also of the usual construc tion.

The vibrating rollers E F F are mounted upon ordinary forked bearings H. The rollers G are also mounted upon similar bearings. (Not shown.) The take-up roller K is provided with a lever-handle I, which is slotted to receive the bolt 17, which connects it with the arm or link N, so as to give it a reciprocating movement by the rotation of the wheel 0, to which this arm N is attached at one side of the center, as at 16,the amount of vibration given to the arm I'being regulated by the bolt 17 and its position. in the slot. This lever or rocking arm is shown enlarged at Fig. 11, where a face and side view are shown. This lever is provided with a pawl 18, which engages with a ratchet-wheel J. (Shown at Figs. 1 and 13.) The lever or arm N is shown in detail in Fig. 14, and the connecting-bolt is shown in detail in Fig. 12. The lever N is provided with a notch or opening 19, which passes over the pin 17 and is locked in place by the pin or bolt 20. The object of this arrangement is so that if at any time an additional quantity of ink is desired the lever N may be detached by drawing the pin 20, when the lever I can be worked by hand to furnish the desired quantity of ink, when it will again be connected and be operated by the link arm or lever N, which gives it one movement by each rotation of the wheel 0, and the roller K is advanced in the inkfountain by means of the ratchet-wheel J and pawl 18, as shown. The ink is also conveyed from the take-up roller to the ink-cylinder by means of the roller K, which is vibrated by means of an arm M, firmly attached to a rock shaft or arm passing through the framing and connected with the arm or lever L, which in turn is operated by the cam 21 on the wheel 0, so as to take the ink from the take-up roller and pass it to the ink-cylinder. This operation, however, is old in printing-presses, so far as this movement from one roller or cylinder to the other is concerned; and my improvement in this respect consists only in connecting its moving arm with the wheel 0. 8 5 The vibrating rollers E F F are mounted in the bearings H, with the usual long journals. The outer end of each of these journals is provided with grooved wheels or sheaves 7, 8, and 9, which are firmly attached to the journals, as shown in Fig. 3. These rollone also rest upon the ink-cylinder B, and are rotated by it. The endwise movement of these rollers is given by the lever 11, (shown in detail at Fig. 10,) which lever is pivoted 95 to the plate 1 at 10. The plate 1 is shown in detail at 4, and is located on the top of the framing, as shown in Fig. 2, it being held in place by suitable bolts and partly sup-= ported by a bracket 2, which fits against the mo slot flattened, as there shown, and by reason head at the opposite end the link-lever N can to the upper end, so that a sufficient vibransual manner.

shown at Fig. 2.

friction roller 22, which rides upon the cam side' of the frame, and is properly bolted thereto. The vibrating lever 11, being pivoted to this plate at 10, has its lower end forked at 14, and each end of the fork is provided with a projection or anti-friction roller 15, which rollers stand in a vertical position astride the wheel 0, and are moved back and forth by the cams 23 and 24. (Shown in detail at Figs. 6, 7, and 8.) The movement of this lever in one direction might be caused by a spring; but I prefer the positive cam movement in both directions, as shown. The upper end of this lever is provided with pins '12 and 13, which respectively engage with the grooved rollers or sheaves 8 and 9. These pins may also be provided with anti-friction rollers, and, as will be seen, the vibration of this lever 11 gives an endwise movement to the rollers F F. A rocking bar or post 4 is also attached to the plate 1 at the bearing 3, which bar, as shown at Fig. 5, is provided with pins or anti-friction rollers 5 and 6. The pin 5 of this rocking bar engages with the under side of the sheave-roller 12, as shown at Fig. 1, and, as the lever 11 moves the roller F and its sheave 12 back and forth the sheave 12 imparts a rocking motion to the arm 4, which in turn, by means of its pin 6 and its connection with the wheel or sheave 7, imparts a longitudinal movement to the roller E, so that by this arrangement the three rollers are given a lengthwise vibration by the lever 11 and the cams 23 and 24 of the wheel 0, and by applying the power to the short arm of this lever a long throw is given tion or lengthwise movement is produced to give the ink a thorough mixing and distribution. The ink is carried from this apparatus to the plate-cylinder O by the rollers G in the Power to drive the ink-cylinder B is appliedto its shaft at the end opposite to the one shown, and power is communicated through said shaft and the pinion P to the wheel 0, which in its rotation by the cams 23 and 24 operates the vibrating ink-rollers, and by the cam 21 the rock-shaft having the arms L M for raising and lowering the roller K and by the wrisrepin 16, link-lever N, and ratchet J operates the take-u p roller K in the ink-fountain D, so that all of these movements are produced 'by the single wheel 0 and the cams thereon. This wheel 0 is attached to the frame A by a suitable stud, as

The pin 17 of the lever I is shown indctail at Fig. 12, which has the portion within the of the thumb-screw at one end and the holdbe locked at any desired position within the limits of the slot.

The lever or arm L is shown in detail at Fig. 9, and it is provided with a pin or anti 21 to lift the roller K. The weight of this roller, which is mounted in the ends of the arm M, is sufficient to keep the pin 22 in contact with the cam 21 without the use of springs or any additional weights, as shown in Fig. 2

and by dotted-lines in Fig. 1.

of the cams 23 and 24, vibrates the lower end of the lever 11 back and forth, carrying with it the rollers F F, while the roller F, by means of the rocking bar 4, also vibrates the roller E. The wristpin 16,being at one side of the journal of the wheel 0, also gives the arm I a vibratin g movement, which, being a lightly working ratchet, rotates the roller K, while the cam 21, roller 22, and lever M lift the roller K into contact with the roller 13, and when in the rotation of the wheel 0 that part of the cam which recedes nearly to the hearing of the wheel permits the roller K to drop back into contact withthe roller K, thus receiving and discharging ink in a uniform manner. of the irregular, reciprocating, or vibrating movements to these rollers by the single wheel 0, thus making a complete, eflicient, and strong inking apparatus which does not re quire any attention on the part of the. oper ator, except in starting, when it may be necessary for a short time to disengage the linklever N and operate the lever I by hand in order to start an additional quantity of ink.

The gear-wheel O is cast with the cams 21, 23, and 24 in one piece, thus facilitating and cheapening the construction of the apparatus as well as making the apparatus more compact and simple in its combination with the other parts, and more eflicient in operation,-
